Bloomberg Businessweek has rejected challenges to its MBA ranking from a Yale University professor who tried to replicate its methodology, reports John byrne of Ports and Quants.

Byrne reports: “The statement comes after an in-depth analysis of the rankings by Anjani Jain, vice dean who oversees the academic programs at the Yale University School of Management. Using WorkweekBased on the scores reported for each school, Jain found that applying the established weights to the five metrics used by the journal would lead to results that are “terribly out of place compared to the published ranking” (see his full analysis here). He calculated that the only way to replicate the ranks published by Workweek is to apply a very different set of weights to the five metrics used to classify programs.

“Jain’s new calculation would change the ranks of 23 of the top 25 business schools. The academic found that applying the indicated weights to the scores published by Workweek would cause MIT’s Sloan School of Management to drop unusually to 21st from 7th; the Jindal School of Management at the University of Texas at Dallas bizarrely soared into the Top Ten, ranking in ninth place, an increase of 22 places, and the Goizueta School of Business at Emory University to achieve its highest rank at 10th. place, eight places better than the published ranking of 18th.

“But a spokesperson for Bloomberg News argues that ‘the premise of Anjani Jain’s analysis and accompanying story (published October 8) in Bloomberg Business WeekThe B-School rating is inaccurate. Both must be corrected. None Poets and Quants nor Yale had access to the raw scores used to calculate the ranking, which Workweek it pointed to Yale several times before the analysis was ‘published’. “
